If a tree falls in the forest, and there's no body there to hear it, does it still make a sound? The answer may surprise you.

  • God I love your voice man!! Whenever I drink a beer I always check out one of your videos. I cant put my finger on it... You have a soothing, intelligent, boomerang way about the way you speak. Its awesome.

  • @mushroomhill Wow, thanks! :)

  • I don't think sound is dependent on the receiver. I'm pretty sure "sound" is the waves through a medium.

  • @tophu1021 Let's put it this way... If there was no life on earth, then there would be nobody to decide that waves produce sound. They are just waves and are meaningless unless someone "hears" them and decides that there is sound. Waves are just waves. Sound is our interpretation or sensation produced by those waves.

  • If you make up a chord that doesn't exist, and play it can you hear that non existing chord or can you not hear it?

  • @diamondyeqy The question is can you make up a chord? You can blend several random note together and call it a chord, but it probably won't sound good, because music is based on math. However, you would still hear it.

  • the vibration is there but the interpretation is lost, much like asking do waves leave marks on a beach if you aren't there to see them....

  • My take on "If a tree falls does anyone here it " is a metaphysical one, If not observed by an aware being ,it reacts differently to our perceived concepts of our reality. Therefore if an aware being with a totally different concept of reality would view it completely different.If no aware being observes it then it just "IS"

  • The existence of sound is a dependent related phenomena, that being it requires something that causes sound and an observer with a hearing capacity to receive it. Everything is dependent related. You can't have one without the other.

  • If sound is the interpretation of vibrations or noise then the questions answer is still no, or more precisely the question is invalid.

    The question asks if a tree falls in the forest does it make a sound?

    If sound is the act of hearing or perceiving vibrating air as sound then trees can't make sound, only noise.
